I started the car up to warm. after the car was warm and ready to go i went about 50 feet to turnaround to head towards a intersection. the car has a sport mode with paddle shifters. i turned off the traction control button and put the car in sport mode went to put the car in 1st gear with the paddle shifter. the car went out of control, i felt the accelerator go to the floor i tried to stop the car with the brakes that did not even slow it down. it happened so fast that did not have time to turn off the engine. i went thru the intersection where i hit a car after i hit the car i was about to unbuckle my seatbelt when the dam air bags went off after the crash
